摘　　要：系统而准确的页岩气储层参数评价对页岩气勘探开发具有重要的指导意义,利用测井资料的连续性建立有效的页岩气储层参数测井评价体系显得尤为重要。探索了页岩气储层的测井曲线定性识别标准,建立了适合该地区的页岩气储层参数定量解释模型,并通过岩心分析资料对部分解释模型加以校正,完成了S1井的页岩气储层识别、总有机碳质量分数、储层物性、含气量以及地质和测井岩石脆性的评价,并借用岩心分析资料加以验证。实际结果表明,该页岩气测井评价体系能够有效的对页岩气储层参数进行评价,可以为该地区后期的页岩气勘探开发提供测井技术支持。It was of great significance for guiding a systematical and precise evaluation of parameters of shale gas reservoirs in shale gas exploration and development.Therefore the application of well logging data continuity for the establishment of shale gas reservoir logging evaluation system was particularly important.The standard of qualitative identification of logging curve of shale-gas reservoirs was studied,models were established for quantitative interpretation of shale gas reservoir parameters in the area and some of the models were corrected through core analysis data,shale gas reservoir identification,total carbon contents,reservoir physical properties,gas content and geologic and well logging evaluation of rock brittleness in Well S1 were verified by using core analysis data.Actual results show that the shale gas well logging evaluation system can effectively assess the shale gas reservoir parameters,it can provide logging and technical support for shale gas exploration and development at the late stage in the region.
